From: o DOT brandt AT tu-bs DOT de (Oliver Brandt) Subject: Re: _ctype_ undefined? 10 Dec 1998 16:18:23 -0800 Message-ID: <366FA189.75757848.cygnus.gnu-win32@tu-bs.de> References: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit To: Mark Fitzgerald Cc: gnu-win32 AT cygnus DOT com This was answered from Mumit somtimes ago: If you use "-mno-cygwin" you need the mingw32-librarys "libstdc++" and (if you use it) "libg++" +"libiberty". Get the whole Mingw32-package from Mumits ftp-site, make a directory "(your CYGWIN-dir)/lib/mingw32" and put (only) the Mingw32-libs in it. You must call gcc now with "-mno-cygwin" and "-L (your CYGWIN-dir)/lib/mingw32" so that this libs would be found. Or (what i've done) change your spec-file, so that the linker found this libs if you use "-mno-cygwin": (...) *link: (...) %{mno-cygwin:-L /(your CYGWIN-dir)/lib/mingw32-lib} I hope that this will help you. But there is still the question: Why is there a switch "-mno-cygwin" and the Mingw32-includes also, but not the libs? Is there the plan to add them in the future to the CYGWIN-package?
